start-stop engine control module-gas or diesel

smhair.gif·I need help to design a control module that would incorporate the parallax basic stamp 2. This module has to sense three different sensors; each one has a high and a low signal;Whenever one of them is high then start engine-and if ever all of them are low then stop engine.
I would like to incorporate an LCD 4 lines display that would read the battery voltage, each sensor: 1-air pressure, 2-oil pressure,3-RPM, 4-time of use for maintenance.
Who could help me with a project like this one, I have been working with stamp since 1996 circa but never achieved a perfect understanding of incorporation of 4 projects at once for example and I know that the basic stamps are powerful enough to achieve what I would like to do and there is no-one here in Montreal, Quebec·who could help me.
yeah.gif·I am a new member and am looking forward to exchange some knowledge.
Thanksburger.gif

    If what you want is the finished project I would offer to pay someone for their efforts. if your wanting to learn and grow from this project then I would start by:

    take each part of this project and break it down into one project. get the code working for each part then work on combining them.

    This site can be a ton of help but the group isn't big on doing stuff for you. give it a shot if you get stuck as a specific question. post your code and you will get help.

    Hi Jamie
    Great show by the way!
    Thank you for your answer. Paying someone to build it is one thing, easier,I convene however I would rather learn and comprehend and I am working really hard at it, never having taken a course. I spend all my sparetime studying and experimenting and am advancing however am having a head-busting time with the coding; but am getting there. As I will progress, I will certainly ask specific questions and advice.
    Your advice for now is very sound, thanks
    Tony

    wow I never look at my signature that way before. I guess I am kinda saying that I'm Jamie Hyneman. I'll have to fix that!

    glad to hear you don't want a buy the project! there should be lots of examples in the manual and online for reading the individual inputs. once you get it reading all of the inputs needed putting them together should be quite easy.

    good luck!

    Are these sensors just high and low? I wonder because you say you want to display values on an LCD. Is it going to be like voltage = Okay or Voltage = 14.1? If it's simply high/low from the sensors for the start and stop logic, look at INS under "Memory Organization and Variables" in the Stamp Editor help file - all you need to do is "read the pins" (you'll likely need some kind of buffering circuitry to protect he Stamp). Otherwise you're probably going to have to use some kind of analog to digital conversion.
